Aluminum die cast- choose the right heat sink

59
One of the most important devices that you should consider owning is heat sink. A heat sink can be used in various systems to provide a cool environment. Mostly, it is used in electrical systems as a passive component which cools a device by dispatching heat into the surrounding air. Some of the major electrical systems that are cooled  using a heat sink include the optoelectrical devices such as  the high powered lasers and lightemitting diodes and he high powered semi conductor devices. Heat sinks are also used in heat exchanger devices such as refrigerators, radiators in auto mobiles and in air conditioning units. When choosing your heat sinks look for the aluminium heat sink as it has a high thermal conductivity which   allows you to have an efficient cooling effect.

What factors affect the efficiency of your heat sink?

When choosing your heat sink it is important thatyou put some factors into consideration. These factors will affect the efficiency of your heat sink. Keep in mind that a heat sink is usually designed to increase the surface area in contact with the cooling fluid surrounding it such as air. Therefore, look for a heat sink whose approach air velocity, fin design and material will have a good thermal conductivity.  Consider looking for a heat sink made from an aluminum die cast.

Why aluminium?

The most common heat sinks are made fromaluminum alloys.   This is because aluminum alloy 1050A which makes the heat sink material has one of the highest thermal conductivity which values at 229W/m.k. Despite the fact the metal is mechanically soft;using themetal to make heat sinks for your light housing will allow having an efficient cooling effect on the device. The metal alloy allows the cooling effect to be done in a fast manner.

Advantages

There are two major benefits of using a die cast heat sink. A die cast heat sink is the type of heat sink that is developed from the aluminum die casting process. One of the majoradvantages is the high volume and a low cost compared to the gravity casting and aluminum sand casting heat sinks. Usingthe aluminum die casting allows the manufacturing company to produce quality precision heat sink parts that are not only durable but also efficient.  Another major advantage of these heats sinks is the good surface finish and good dimensional accuracy. The aluminum die casting allows your heat sink to have a good surface finish which eliminates most of the post machining parts.

Maintenance

Aluminium die cast heat sinks have a wide range of applications on the   thermal conductivity products. It is important ant   to ensure that your heat sink is well attached. The method of attachment used and the thermal interface materials used will have an effect on the die temperature of the integrated circuit. Using thermal adhesive or thermal grease to fill the air gaps between the heat sink and the device allows you to improve its thermal performance.  You can consult a technician to help you determine the thermal efficiency of your heat sink.
